[Cartoweb-users] Problem creating new layers

[Nicolás Eugenio Ozimiça]

I've tried what you told me Oliver, but with no success.

With the lines you gave:
$msLayer =
$this->serverContext->getMapObj()->getLayer($result->layers[0]->index);
$msLayer->set('status', MS_ON);

I also included these other lines:
$msLayer->set('type', MS_LAYER_RASTER);
$msLayer->setProcessing("BANDS=1,2,3");

because the layer I try to create is a raster image.

The only solution I see is having a set of empty layers in the mapfile (and
also in the layers.ini), hidden from the menu layer tree, that when a user
specifies a raster to be shown, is "put" in the first empty layer available.
But this is something here we don't like very much.

I'm using ajax, but I made a test without it, and no result either...

Has someone else had trouble tring to create a raster layer with MapOverlay?
